Phacoemulsification versus Phacotrabeculectomy in Medically Controlled Primary Angle Closure Glaucoma with Cataract in an Indian Cohort: A randomized controlled trial.
Trial report in International ophthalmology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo compare the outcomes of phacoemulsification with phacotrabeculectomy in primary angle closure glaucoma (PACG) eyes with medically controlled intraocular pressure (IOP).
methodsProspective, randomized control trial including 33 eyes of 33 patients who underwent phacoemulsification (Phaco) and 37 eyes (37 patients) who underwent phacotrabeculectomy (PT). The primary outcome measure was survival defined as IOP control (IOP ≥ 6 and ≤ 21 mmHg without antiglaucoma medications (AGM) at different time points. Secondary outcome measures were the rate of visual recovery and complications.
resultsThe mean age in years (PT: 58.5 ± 9.8, Phaco:61.6 ± 8.9; p = 0.16), preoperative mean deviation in decibel (PT: -18.7 ± 9.3; Phaco: -16.6 ± 7.9; p = 0.32) and the mean follow up in years (PT: 2.5 ± 1.8; Phaco: 2.8 ± 2.0; p = 0.63) were similar in the two groups. The mean preoperative AGMs were more in the PT group (PT: 2.13 ± 0.97, Phaco: 1.60 ± 0.78; p = 0.01). In both the groups the survival was similar at all-time points (PT: 78% at 1-year and 52% at 5-years, Phaco: 80% at 1 year and 59% at 5 years (P = 0.82). The postoperative visual acuity in LogMAR was significantly better in the Phaco group at 1 month (PT: 0.22 ± 0.38, Phaco:0.06 ± 0.07; p = 0.02). Postoperative AGM (p = 0.68) and rate of visual field progression PT: -0.46 ± 0.41 dB/year; Phaco: -0.38 ± 0.73 dB/year; p = 0.67) were similar in both groups. One eye in PT group developed malignant glaucoma which resolved with laser hyaloidotomy and cycloplegic therapy.
conclusionsMore rapid visual recovery with similar IOP control and similar visual field stability favor phacoemulsification to phacotrabeculectomy in medically controlled PACG eyes with cataract.
